Notice of the 44th "Latest Construction Method and Technology Training Seminar"

I would like to report on a new initiative that utilizes the cutting function of steel obstacles.

Yasuda Engineering Co., Ltd. will conduct a seminar at the 44th "Latest Construction Technology Seminar on Advanced Propulsion Methods" held in Tokyo and Osaka. We will report on our new initiatives utilizing the steel obstacle cutting function of the milling mole method. This seminar is accredited as a "Continuing Professional Development (CPD) Program" by the Japan Society of Civil Engineers. (CPD credits: 6.5) We sincerely look forward to your attendance. [Overview] ■ Seminar Time: 14:55 - 15:50 ■ Seminar Content: Challenging New Areas with the Milling Mole Method - New Initiatives Utilizing the Steel Obstacle Cutting Function - *For application details, please refer to [Details on How to Apply for Participation Here]. *For more information, please refer to the PDF document or feel free to contact us.

• Special Construction Method

It is possible to directly reach the existing shield through the application of metal cutting technology! We are currently presenting examples of construction where direct cutting was performed on existing shields.

The "Milling Mole Method" is equipped with a specialized bit designed for cutting through obstacles using a tunneling machine. It allows the cutter of the tunneling machine to make ultra-low-speed contact with obstacles through a special telescopic pipe, enabling cutting through the rotation of the cutter. This operates on the same principle as lathe machining. A significant feature of this construction using the "Milling Mole Method" is that it achieved direct cutting of steel segments without performing mirror cutting. Since improvements to the protective measures of the existing shield section could not be made from the surface, a boring machine was mounted, allowing for injection from within the tunneling machine (using a dual-pipe strainer method with multiple phases). Additionally, a formwork for cutting connection was installed inside the existing shield, and fluidized treatment soil was placed, allowing for direct cutting at ultra-low speeds and safely avoiding the risks of water inflow and subsidence accidents that occur during mirror cutting. Previously, mirror cutting was performed from within the shield, raising concerns from customers about the risks to the surrounding environment due to groundwater inflow and ground collapse associated with that construction. We proposed direct cutting of the existing shield, and after executing the construction, we successfully reached the target without affecting water inflow or the surrounding environment, resulting in great satisfaction from the client! 《You can download the construction case from the PDF below!》

Introducing a case study of shield arrival construction using the milling mall method!

The "Milling Mole Method," equipped with four special functions: exploration, improvement, cutting, and guidance, is a ground obstacle response type mud-based thrusting method. It consists of three devices: a tunneling machine, a special telescopic pipe, and a special injection pipe, allowing for the precise cutting and removal of underground obstacles. In the construction of the inflow pipe sewer system for the second Nakagawa Chubu rainwater adjustment pond, the Milling Mole Method was used to carry out the shield arrival work. Milling cutting length: The assembly precision of the steel formwork at the arrival section inside the existing shield, L=1.520m from the outer circumference of the existing shield, was excellent, and there were no leaks of groundwater or muddy water during the placement of fluidized treated soil or during the shield cutting with the tunneling machine, allowing for safe cutting. 【Construction Example】 ■Location: Nagoya City, Aichi Prefecture ■Client: Nagoya City Waterworks Bureau ■Contractor: Asanuma Corporation ■Nominal Diameter: φ2200mm ■Thrusting Length: 101.520m ■Underground Obstacles: Direct access to the existing shield Inner diameter of the existing shield φ3750mm *For more details, please refer to the PDF document or feel free to contact us.

You can see the basics of handheld laser scanners, actual data acquisition using "FLIGHTS SCAN HANDY," and the analysis of the acquired data. Additionally, we will explain the fundamentals of drone-mounted LiDAR. You can also see the creation of terrain-following flight plans using "FLIGHTS PLAN" and the analysis of data obtained with "FLIGHTS SCAN." If you are considering the introduction of handheld devices as supplementary surveys for drone-mounted LiDAR or ground-based lasers, or if you want to improve the efficiency of supplementary surveys, please take this opportunity to participate.

Realizing efficient infrastructure management through point cloud data.

"I want to know what can be done with AWS." "I am interested in cloud adoption, but I have concerns about security and costs..." This is an introductory seminar for representatives of small and medium-sized enterprises, where you can learn the basics and case studies of utilizing AWS Cloud in just one hour. We will explain the fundamentals of AWS Cloud and the benefits of adoption, as well as introduce specific use cases for small and medium-sized enterprises. Additionally, we will clearly explain the first steps for implementation and provide tips that can be put into practice starting tomorrow.

Speed Roll Co., Ltd. (Headquarters: Chuo-ku, Tokyo; CEO: Yang Cai) will exhibit at the "JAPAN PACK 2025 - Japan Packaging Industry Exhibition" to be held at Tokyo Big Sight from October 7 (Tuesday) to October 10 (Friday), 2025. At our booth, we will showcase three models of automatic packaging machines that innovate the bagging, sealing, and labeling processes for e-commerce logistics: ◆ Speed Roll Air: Suitable for bagging into cushioned envelopes ◆ Speed Roll Hybrid: An automatic bagging machine compatible with paper bag packaging ◆ Speed Roll Carton: Achieves automatic sealing and labeling for random sizes, from post-in sizes to cardboard boxes up to 420mm in height We also offer a rental plan starting from 50,000 yen per month. This rare plan in the industry allows for implementation while keeping initial investments low, and it has received positive feedback from many companies. We invite you to take this opportunity to see the actual machines and experience the implementation image on-site. All of our employees sincerely look forward to your visit.
